To all whom it may concern:

Be it known that I, h IIoIIAnL C. Granny, a citizen of the United States of America, residing at Hoosick Falls, in the county of Rensselaer and State of New York, have invented new and useful Improvements in GraiirLifting Attachments for Harvesters, of which the following is a specification.

This invention. relates to. grain lifting attachments for harvesters, and it has for its object to provide a device of simple and ellicient construction which may be readily attached or applied to practically any well known type of harvester as well as mowers and reapers in ordinary use.

A further object of theinvention is to provide a simple and improved supporting means which will enable the grain lifting attachment to be readily applied or removed, as may be desired.

A. further object of the invention is to simplify and improve the manner of attaching and mounting the lifting finger.

Still further objects of the invention are to simplify and improve the general construction and operation of a device of the character described.

lVith these and other ends in view, which will readily appear as the nature of the invention is better understood, the same con sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawings,-I+igure 1 is a side elevation showing the improved device applied to the finger bar and guard of a harvester, the finger bar being shown in section. Fig. 2 is an enlarged top plan view of the rear portion of the device. Fig. 3 is a longitudinal vertical sectional view taken on the line 33 in Fig. 2. Fig. 4 is a sectional elevation, showing the device with the arm raised for the purpose of detaching it from the harvester. Fig. 5 is a sectional detail view taken on the line 5-5 in Fig. 1, through the lifting bar and holder. Fig. 6 is a perspective View showing the bearing member detached.

Corresponding parts inthe several; figures are denoted by Like characters of reference,

Secured upon the finger bar 1 by means of a fastening member, such as a bolt 2, is a bearing member 3. which extends f(,)r\\"ardly of the finger bar and. is provided intermediate the ends thereof with a downwardly extending lug 4-. adapted to engage the upper face of the cutter bar for the purpose of assisting in retaining the knives in. proper position. Said bearing member is also provided adjacent to the ends thereof with for wardly extending lugs or offsets forming shoulders 4:. The bearing member is. provided with a groove or channel 6 which is of approximately circular cross section and provided with overhanging flanges7 to constitute a bearing for the crossbar 8. of a yoke 9. Said yoke is provided with notches 10 which, when the yoke is raised to the position indicated in Fi 4., will register with the overhanging flanges 7, thus enabling the yoke to be slid or moved laterally into or away from the groove 6 which constitutes the boxing or bearing for the cross bar 8. As soon as the yoke is lowered, the notches 10 will pass out of register with the overhanging flanges 8, and the yoke, the limbs of which are now supported on the shoulders or o'il'sets l, will become firmly locked in its bearing.

Suitably bolted upon or otherwise connected with the yoke 9 is a forwardly extending angle bar 10 which constitutes the auxiliary lifting arm, and suitably bolted or otherwise secured upon the front end of said angle bar or lifting arm is the holder 11 for the lifting finger 12. Said holder is formed with a terminal point 13 at the front end thereof, and it has a vertical wall or web ill provided at the rear end thereof with a diagonally disposed flange 1:") having a plurality of apertures 16. The wall or web 14L also has an aperture 17 for the passage of a lug 18 at the forward end of the finger 12. The body of the said finger 12 may be passed through any one of the apertures 16 in the diagonally disposed flange 1."), after which the lug 18 may be projected through the aperture 17 and secured by means of a cotter pin 19. The lifting finger will thus be sustained securely in position for operation, and its elevation may be changed by shifting it from one to another of the apertures 16.

A lever arm L having intermediate its ends an offset 20 is projected through a slot 21 in the angle bar The upper end of said lever arm projects forwardly and has a terminal hook 22 connected with one end of a spring 23, the opposite end of which is secured upon the angle bar. The lower end of the lever arm L projects rearwardly and has a terminal socket 2 1: for the reception proper position for operation, but in a yieldmg or resilient manner, the forward end of said arm being capable at all times of yield ing in an upward direction. Movement of the arm 10 in a downward direction is limited by the shoulders or offsets 4 which support the limbs of the yoke 9 with which said arm is associated, thereby makingit impossible for said arm to move downwardly below a predetermined limit, and relieving the spring actuated lever L from undue strain. The socketed portion of the lever L will serve to deflect material beneath the guard finger so that the progress of the machine will not be obstructed. To detach the device, the arm 10 is raised to the position shown in Fig. 4, when the yoke 9 may be moved laterally out of engagement with the bearing member 3.

. Having thus described the invention, what is claimed as new, is

In a grain lifting device for harvesters, a bearing member secured upon and extend ing forwardly from the finger bar, said bearing member having a downwardly extending lug intermediate the ends thereofengaging the cutting apparatus and forwardly extending lugs adjacent to the ends thereof,

Cir

said bearing member being also provided with an approximately circular groove or channel with overhanging flanges, in combination with a yoke having a cross bar of circular cross section pivot'ally engaging the bearing and provided adjacent to one end of the cross bar with notches adapted to register with the overhanging flanges of the bearing member when the yoke is in araised position, and a lifting arm connected with the yoke, the limbs of said yoke being sup ported when the yoke is ina lowered position on the forwardly extending lugs or offsets of the bearing member.

In testimony whereof I affix my signature in presence of two witnesses.
